The T+A DAC 200 combines a top-of-the-line DAC, preamp, and headphone amplifier. The device's circuit uses full galvanic isolation of the digital and analog parts, as well as the “double mono" principle. The original Double-Differential-Quadruple Converter solution with a switchable digital filter is used to convert PCM signals (up to 32/768). Whereas there is a separate T+A True 1-Bit module for DSD, which supports up to DSD1024. Optionally, the DAC 200 can be equipped with an HDMI card (2 inputs, 1 output) with an ARC reverse audio channel.
